Ive asked around, and my friends tell me that im goan need to setup some hardware stuff on the comp for it, and for them its gona take abt a month........yikes.
They mentioned that the programs used are LabView and Matlab (Matlab is a program where you can write scripts to do maths or control parts of your computer). They recommended me to look for Science or engineering students since these students mustve used these programs before. WEll...if we ever go through with my idea, i'll look into finding helpers from differnet faculty.
Anyway, for the walls in the exhibition, i wanted a glass/transparant rectangular LED lite wall right? yeh...well, ive found an instructable that is sorta doing what i was looking for...except her work was done using cardbox.

If the pricing is too expensive for the first idea, then maybe we can try this one instead. Still works the same, but a little less light for the environment.

And as for the platforms that students will used to display their work, im thinkin of using large blocks of clear acrylics cut into different shapes. Then we'll place lighted LED at the bottom to shine through it.


But yea, i still haev yet to find out how a color changing lamp works.
I wanted to use an idea similar to this for some parts of the wall or for the floor. FOr hte walls, i wanted to place color changeable lgihts (circular) so that when people touch it, it'll change color, creating interactivity in the environment. As for hte floor, i want the colors of the light to change hwen someone steps on it...i guess that has sth to do with pressure sensing. The difference between the video and my idea is that the lamp in the video changes colors itself aswell once it is turned on. I dont want that....i want the lights of the installation to change only when it is touched.
